I applied through my university's career portal and followed the instructions to also create a profile online and apply to each location I wanted to be considered for. Honestly, the hardest and most surprising questions of the entire process was remembering my PSAT and SAT scores. Do not remember time difference between first interview and application submission.
1st round interview- Interview was approximately the second week of the month. Read to you like a script. Short, and is based on a few short questions and thanks to reading the reviews beforehand, there wasn't much for me to be surprised by. Questions were straightforward and simple. Nothing surprising at all. In fact, they were so simple, I was afraid there would not be much information to use to help me land the second round. My interviewer was pleasant but hard to read and I think my experience, ability to find some way to connect with him, and my follow up made all the difference. A few days later, I was offered an opportunity for a second round interview for a few weeks later.
2nd round interview- JP Morgan must interview in batches because I was there with approximately 11-15 others. Each person has two personal interviews that day with company leaders (managers, directors, VPs), a group activity (which is essentially a group interview), and a break. Again, the questions are read from a script but my interviewers made it more conversation based than the first interviewer.
The group activity would probably be the most intimidating factor. Groups of 6-8 sit around a conference table with the group of interviewers in a circle on the perimeter monitoring and taking notes. The activity varies each time apparently, so mine cannot help. I would be curious to find out who received an offer, but as you can imagine there will be people who are naturally aggressive and take lead in their attempt to stand out and those who are more reserved and quiet. I would like to note though, that one of the biggest mistakes people seemed to make was underestimating people based on their initial impression and forgetting to include more timid people and vouching for them to be heard. Our activity required everyone's contribution so you cannot ignore people. I think if you remember that, you'll be set.
Additional tips: Be yourself, whoever that is and remember to be courteous and thoughtful and try to make genuine connections with everyone. Hopefully you are naturally that way.That includes the other people you interview with. They are not competition and should you be so fortunate as to be extended an offer, those same people could very likely become your coworkers, bosses, or best friend one day. Its important to keep the camrarderie.
Received an offer exactly one week later. Hope this helps! I know how stressful it can be.
